Elliptic Geometry
Riemannian Geometry

A non-Euclidean geometry in which there are no parallel lines. This geometry is usually thought of as taking place on the surface of a sphere. The "lines" are great circles, and the "points" are pairs of diametrically opposed points. As a result, all "lines" intersect.
